Hey, what's the worst that can happen, I learn nothing. More likely I'll learn something on a macro scale that provides some useful information. I probably learn more from doing literature searches and relying on trusted sources, but it's so much FUN to play with science! Just the mental effort to design an experiment, carry it out and interpret the results is worthwhile even if the results aren't useful. It's good thinking practice. That's why I opened the project to everyone who wants to be involvement or have input. I sure don't know what I'm doing, but that's never stopped me yet!
